I-Weld Neck Flanges kunye ne-Slip On Flanges--BS3293

UmGangatho waseBritani BS 3293: 1960-Iintsimbi zeCarbon Steel Pipe (ngaphezu kwe-24 intshi yobukhulu obuqhelekileyo) kuShishino lwePetroleum, lugubungela iKlasi ye-150lb ukuya kwi-600lbweld intamo flangeskwayetyibilika kwiiflange.

Oku kulandelayo kuya kwazisa imilinganiselo kunye nokunyamezelaukuwelda intamo flange kunye nentamo flat welding flangekwiBS 3293.

I-BS3293 weld intamo kunye nokutyibilika kwi-flange yeyenkqubo esemgangathweni ye-flange yaseMelika.Kukubonakaliswa kwe-American standard flange (eyaziwa nangokuthi indlela ye-ANSI) kunye nenye yeeflange ezisetyenziswa ngokuqhelekileyo kwisixhobo okanye kwipayipi.

I-BS 3293: 1960 yimpahla kunye nobukhulu.Lo mgangatho usebenza kuphela kwintsimbi ye-carbon carbonI-slip-on flange kunye ne-welded neck flange ye-diameter ye-nominalI-intshi ezingama-26 nangaphezulu kwipetroleumI-industrial drilling, bolting, ukugqiba kunye nobukhulu
Imilinganiselo iyasebenza nakwiziphelo ezidityanisiweyo.
Iiflange zeevalvu kunye nezifakelo.Iintlobo ezine zeeflange zibonelelwa, ezizezi: iklasi150, 300, 400 kunye ne-600. I-BS 3293: 1960 ayibandakanyi: ukulinganiswa koxinzelelo / ubushushu;Igama lesalathiso seflange lisetyenziselwa iinjongo zokuchonga
Isalathiso somnqamlezo kuphela: BS 1503, BS 1560, BS 1750, BS 3351, ANSI B16.20, ASTM A 105

Umahluko phakathi kwe-Weld Neck Flanges kunye ne-Slip On Flanges
1. Iifom ze-weld ezahlukeneyo:
Ukuhlolwa kwe-Radiographic kungenziwa kwi-welds ye-welding ye-welding ye-flange yentamo, kodwa kungekhona kwi-flange ye-flange ye-welding.Ifom ye-welding ye-neck butt-welding flange kunye nombhobho i-weld circumferential, ngelixa ifom ye-welding ye-flange ye-welding kunye nombhobho i-fillet weld.I-butt welding yi-weld ye-butt circumferential, kunye ne-flat welding yi-welds ye-fillet circumferential.Umahluko phakathi kwezi zinto zimbini kukuba intsimbi yokuwelda intsimbi yentamo ye-butt-welding flange kunye nomlomo we-Class B we-weld, ngelixa i-weld edibanisa i-flange ye-neck-welding flange kunye ne-nozzle ye-Class C seam.
2. Iimathiriyeli ezahlukeneyo:
Izinto eziphathekayo ze-flange ye-welding ye-neck butt zihlala zenziwe ngeengxenye zetsimbi ezenziwe ngomatshini.Izinto eziphathekayo ze-slip-on welding flange enentamo zenziwe ngeplate yentsimbi eqhelekileyo kunye nobukhulu obufunekayo ngokusebenzisa umatshini.
3. Uxinzelelo lwegama olwahlukileyo:
Uxinzelelo lwegama lentamo ye-butt-welding flange yi-1-25MPa, ephezulu.Uxinzelelo oluncinci lwentamo ye-flange ye-welding flange yi-0.6-4MPa.Xa kuthelekiswa nentamo yeflange ye-welding, inqanaba loxinzelelo lisezantsi kwaye ukukwazi ukuziqhelanisa noxinzelelo nako kusezantsi.
